Why not? A.J is large and powerful, I think he might KO Ali from 70 ies! Look how he looked vs Pulev in first 3 rounds!
Ibeabuchi beat two good young undefeated heavyweights who had different styles. If we could have gotten the Lennox match or a Klitscko match before Ike had his downward spiral we would have a much better picture of how Ike matches up to a lot of these guys today (and in the past). But that wasn't in the cards. Still with that said, you have to have some real talent to do what he did to Byrd and Tua at that time(though the Tua fight was close and Ike fought a pretty insane gameplan). i dont think Joshua can keep Ike off of him forever and AJ will not like trading with Ibeabuchi, which is what eventually will happen. Ibeabuchi KO7/8 after AJ doesn't come out for the next round.
